发明名称 Detergent formulations free of phosphates, zeolites and crystalline layered silicates
摘要 The present invention relates to detergent formulations which contain (a) 3 to 70% by weight of one or more surfactants; (b) 1 to 60% by weight of a readily biodegradable copolymer which comprises monomer units obtained from (A) monoethylenically unsaturated dicarboxylic acids, anhydrides, salts thereof or mixtures thereof, (B) monoethylenically unsaturated monocarboxylic acids, salts thereof or mixtures thereof, (C) monounsaturated monomers which aqueous polymerization, after hydrolysis or saponification, give monomer units which have one or more free hydroxyl groups on a carbon chain of the copolymer, and (D) 0 to 15% by weight of one or more further monomers capable of free radical copolymerization; (c) 0 to 60% by weight of washing alkalis; and (d) 0 to 70% by weight of standardizing agents, and their use in inhibiting incrustation of textiles and in removing alkaline earth metals from textiles during laundering.
